Smokeless grilling oven

ABSTRACT

A smokeless grilling oven is disclosed. The oven comprises a grate, a frame body, a plurality of infra-red heaters which equals the number of sides of the frame body, and a slanting securing rack for mounting the heaters, wherein the grate is placed onto the frame body and the bottom edge of the frame body suspends the slanting securing rack and the infra-red heaters are mounted onto the slanting securing rack so that the emitting end of the heater is slopingly facing the bottom of the grate.

BACKGROUND OF THE INVENTION

(a) Technical Field of the Invention

The present invention relates to a smokeless grilling oven of abarbecue, and in particular, a grilling oven employing infra-red to heata grate and its surrounding space and the food placed on the barbecuingnet.

(b) Description of the Prior Art

Barbecuing is a method of cooking food which normally has a smoked smellwhich is rather tempting. Conventionally, the grilling oven of thebarbecuing stove employs charcoal as the burning material, and a gratemounted onto the opening of the oven. In the course of barbecuing offood, the dripping of barbecuing sauces or the liquid fat from meat willdrop onto the burning charcoal which will reduce the charcoal'stemperature. The smoke formed during barbecuing will pollute theenvironment and affect the respiratory system of people exposed to suchan environment.

However, charcoal produces the greatest heat and best grillingefficiency. To avoid barbecue sauce form dripping onto the burningcharcoal, the charcoal is normally placed at one side of the oven to beaway from the center of the barbecuing rack, but the heat generated bythe burning charcoal will be gathered to move upward. This will noteffectively heat up the food. Additionally, when charcoal is employed inbarbecuing, the formation of smoke or ash cannot be avoided andpollution to the environment remains a problem.

Even though some people feel that barbecued meat with a smoked smell hasa better taste and the surface of the barbecued meat is crispy, this isnormally true only if the heat is appropriately controlled, wherein thebarbecued meat will have a good smell. When using a conventionalbarbecue stove to barbecue meat, if the smoke pollutes the meat it isnot healthy to consume it. Therefore, it is an object of the presentinvention to provide a smokeless grilling oven.

SUMMARY OF THE INVENTION

Accordingly, it is an object of the present invention to provide asmokeless grilling oven comprising a grate, a frame body, a plurality ofinfra-red heaters which equals the number of sides of the frame body,and a slanting securing rack for mounting the heaters, wherein the grateis placed onto the frame body and the bottom edge of the frame bodysuspends the slanting securing rack and the infra-red heaters aremounted onto the slanting securing rack so that the emitting end of theheater is slopingly facing the bottom of the grate.

Yet another object of the present invention is to provide a smokelessgrilling oven, wherein infra-red radiation is used to roast food insteadof burning charcoal. In this instance, there is no incomplete combustionor no burning ash flying around to contaminate the environment. Thus,the entire roasting process can be easily achieved.

The foregoing object and summary provide only a brief introduction tothe present invention. To fully appreciate these and other objects ofthe present invention as well as the invention itself, all of which willbecome apparent to those skilled in the art, the following detaileddescription of the invention and the claims should be read inconjunction with the accompanying drawings. Throughout the specificationand drawings identical reference numerals refer to identical or similarparts.

Many other advantages and features of the present invention will becomemanifest to those versed in the art upon making reference to thedetailed description and the accompanying sheets of drawings in which apreferred structural embodiment incorporating the principles of thepresent invention is shown by way of illustrative example.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following descriptions are of exemplary embodiments only, and arenot intended to limit the scope, applicability or configuration of theinvention in any way. Rather, the following description provides aconvenient illustration for implementing exemplary embodiments of theinvention. Various changes to the described embodiments may be made inthe function and arrangement of the elements described without departingfrom the scope of the invention as set forth in the appended claims.

FIG. 1 is a perspective view of a smokeless grilling oven and FIG. 2 isa perspective exploded view of the grilling oven in accordance with thepresent invention. The smokeless grilling oven 10 comprises a grate 20,a frame body 30, a plurality of infra-red radiation heaters 40, 41 andthe number of the heaters 40, 41 being equal to the number of sides ofthe frame body 30, and slanting securing racks 50, 51 for securing theheaters 40, 41. The frame body 30 is formed from conduits 31, 32, 33, 34enclosing to form the frame body 34, and at least a pair of the conduits31, 32 have a relative edge protruded inward to hold the holding plate35, 36 of the grate 20 so that the grate 20 can be placed at the framebody 30. The bottom of the side of the frame body 30 is soldered orfastened with slanting securing racks 50, 51 and the infra-red heaters40, 41 are mounted on the securing racks 50, 51. The securing racks 50,51 adhered with the heat emitting ends 42, 43 of the heaters 40, 41 areformed into through holes 52, 53 having area similar to that of theheat-emitting ends 42, 43 so that the heat emitting ends 42, 43 areslopingly facing the bottom of the grate 20. Thus, the infra-redradiation is used to grille the grate 20 and the surrounding of thegrate 20 to heat food on the grate. The oil of the food and thebarbecuing sauce applied to the food stuff on the grate will passthrough it but will not drip onto the heat-emitting ends 42, 43. Thus,the surrounding environment will not be polluted in the course ofbarbecuing.

FIG. 3 is a front view of the oven and FIG. 4 is the top view of thesmokeless grilling oven in accordance with the present invention. Thegrilling oven 10 is mounted onto a stove 60. Due to the fact that nosmoke is generated, it can be used in the home.

As shown in FIG. 5, the slanting securing frame 50, 51 connecting oneend of the frame body 30 is vertically extended to form suspension rods54, 55 so that the heat-emitting ends 42, 43 of the heater 40, 41 areslopingly extended to the center position of the grate 20.

As described above, the present invention provides a smokeless grillingoven, wherein infra-red radiation is employed to grille the grate andthe surrounding of the grate and to heat the food on the grate. The oilfrom the food stuff and the barbecuing sauce will not drip onto theheat-emitting end of the heaters.

It will be understood that each of the elements described above, or twoor more together may also find a useful application in other types ofmethods differing from the type described above.

While certain novel features of this invention have been shown anddescribed and are pointed out in the annexed claim, it is not intendedto be limited to the details above, since it will be understood thatvarious omissions, modifications, substitutions and changes in the formsand details of the device illustrated and in its operation can be madeby those skilled in the art without departing in any way from the spiritof the present invention.
